23、 anybody can do it! Perhaps this sounds crazy, but it's true. Maybe you have the wrong idea about inventing, so read on to discover the truth. Wrong idea No. 1: An invention has to be something completely new. Inventing means creating something "new", but the idea could come from s

24、omething that already exists(存在). The Wright brothers, for example, got the idea for building a "flying machine" from watching birds. Wrong idea No. 2: Inventors are born, not made. There are a lot of factors(因素) that make invention possible. Take Mazart, for example. He was born w

25、ith a talent for musical composition. But other factors were also important for his creativity. His father was a music teacher, and Mozart practiced for hours every day, from the time he was four years old. Thomas Edison said that being an inventor was "99% hard work and 1% inspiration"! Ve

26、ry successful creators don't give up when they get something wrong. As one inventor said, "A failure is the right answer to the wrong question." Wrong idea No. 3: Inventors are always old people. Don't believe that you can't invent something when you are young. Here are two example

31、he rain. Its first use was as a shade(遮蔽) against the sun. Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, back in the eleventh century BC. We know that the umbrella was used in ancient Egypt and Ba

32、bylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and power(權(quán)力). In the Far East in ancient times, the umbrella was allowed to be used only by those in high office or by royal people such as the kings or queens. In Europe, the Greeks were

33、 the first to use the umbrella as a sunshade. The umbrella was in common use in ancient Greece, but it is believed that the first people in Europe to use the umbrella as protection against the rain were the ancient Romans. During the middle ages in Europe, the use of the umbrella almost disappeared.

34、 Then it appeared again in Italy in the late sixteenth century. And again it became a symbol of power. Umbrellas have not changed much in style during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that the umbrellas for women began to b

38、he invention of the umbrella D. the history and the use of the umbrella C Thomas Edison was a great American inventor. He was born to a poor family in 1847. His mother taught him at home. He often observed things carefully and he made over 1,300 inventions during his life time. He was o

39、ften said to be the greatest genius(天才) of his age. There are only a few men in all of history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius. “There is no such thing as ge

40、nius,” Edison said. He also said that what people called genius was mostly hard work. But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to lea

41、rn what could usefully be done with them. Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure. Edison c

42、ould not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. “Work,” he answered back, “discovering the secrets of nature and using them to make men happier.” He said he h

46、live and work for 100 years D 1970 was World Conservation Year. The United Nations wanted everyone to know that the world is in danger. They hoped that governments would act quickly in order to “conserve” nature. Here is one example of the problem. At one time there were 1,300 different pl

47、ants, trees and flowers in Holland, but now only 866 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and water, and everything that grows and lives. We can't live without these things. If we continue like this, we shall destroy ourselves.
